Update database table based on textbox values

[Lordemotara]

I am trying to update database table based on text-box values.But i am unable to get new modified values in database.Here is my code which displays information in text-boxes coming from database\[code\]protected void Info(){ string sID = Request.QueryString["ID"]; string sSql = "select * from [fn_Items]('"+sID+"')"; DataTable tbl1 = new DataTable(); string sEr = myClass.FillupTable(sSql, ref tbl1); if (tbl1.Rows.Count > 0) { DataRow rd = tbl1.Rows[0]; txtName.Text = rd["Name"].ToString(); txtCategory.Text = rd["Category"].ToString(); DateTime mStart; DateTime mFinish; Boolean b = false; b = DateTime.TryParse(rd["start"].ToString(), out mStart); b = DateTime.TryParse(rd["end"].ToString(), out mFinish); txtStart.Text = mStart.ToString("dd-MMM-yyyy"); txtend.Text = mFinish.ToString("dd-MMM-yyyy"); txtDescription.Text = rd["Description"].ToString(); }}\[/code\]Now when the user modifies the text-box data and clicks save, the data should change in the database. Here is my click_event:\[code\]protected void btnSave_Click(object sender, EventArgs e){ using (SqlConnection sqlConn = new SqlConnection("Data Source=MSSQLSERVER2008;Initial Catalog=Items_2;Persist Security Info=True;User ID=sa;Password=password")) { string query = "UPDATE tbl_Items SET Name = @Name,Category=@Category,start = @start, end = @End,Description = @Description where ID = @ID "; SqlCommand cmd = new SqlCommand(query, sqlConn); cmd.Parameters.AddWithValue("@ID",txtID.Text); cmd.Parameters.AddWithValue("@Name", txtName.Text); cmd.Parameters.AddWithValue("@Category", Category.Text); cmd.Parameters.AddWithValue("@start", txtStart.Text); cmd.Parameters.AddWithValue("@end",txtend.Text); cmd.Parameters.AddWithValue("@Description", txtDescription.Text); cmd.Connection.Open(); try { cmd.ExecuteNonQuery(); } catch (Exception ex) { throw new Exception("Error " + ex.Message); } }\[/code\]Here while updating, in text-boxes I am getting the values present in the database where I need to get the modified values. How do I get the modified values instead?
